Abstract Scope |
Additive manufacturing enables the production of complex lightweight components. However, the poor usage of atomized metal powders is a challenge, as fine particles must be removed from the powder feedstock to ensure flowability. Further new high strength aluminum alloys are needed. Some investigations show that the mechanical properties of AlSi10Mg can be improved by adding TiC nanoparticles. The aim of this study is to determine if the influence of small amounts of TiC additions, which are normally used to improve the flowability of fine powders, is also sufficient to improve the mechanical properties. It was found that the addition of 0.46 wt% TiC-Nanoparticles with a size of 50 nm led to a homogeneous grain size distribution and an increase of 16 % in yield strength compared with pure AlSi10Mg. Further a strong median grain size reduction from 5.08 to 2.74 µm could be observed by adding 0.96 wt% of TiC-Nanoparticles. |
